What Iceberg Table Maintenance Actually Costs
A cost model for compaction, snapshot expiry, orphan cleanup, and manifest rewriting: what each operation spends, on which meter, and how to set a schedule.

Running an Iceberg Lakehouse on Kubernetes
Catalog, maintenance, and compaction as Kubernetes workloads: scheduling classes, job structure, credential flow, and the failures that come from the interaction.
-
The Hidden Cost of Tiny Iceberg Commits
Trace what one tiny Iceberg commit writes, then model hourly, per-minute, and per-second cadences so streaming costs become arithmetic, not adjectives.

Autonomous Table Optimization When Your Query Workload Stops Being Predictable
Autonomous table optimization when query workloads stop being predictable: observing file layout and query patterns, scoring compaction work, adaptive.
-
Table Maintenance Stopped Being a Product
Iceberg table maintenance commoditized when every platform started shipping it. What the six operations are, what they cost, and the observability you.
